MIPS: unaligned: Fix regular load/store instruction emulation for EVA
When emulating a regular lh/lw/lhu/sh/sw we need to use the appropriate instruction if we are in EVA mode. This is necessary for userspace applications which trigger alignment exceptions. In such case, the userspace load/store instruction needs to be emulated with the correct eva/non-eva instruction by the kernel emulator.
